Embodiment Construction

[0042] exist Figure 1 to Figure 12 The band-type pipe wrench 10 shown in is mainly used for dismantling and concomitantly tightening generally cylindrical objects 11, in particular oil filters, the diameter of which can be within a wide range by turning the pipe wrench Variations, such as a diameter of 64 mm to 106 mm in the embodiment shown.

[0043] To describe the pipe wrench 10 more conveniently, it is assumed that the pipe wrench is placed in the orientation shown in the figure, which extends along the longitudinal axis X-X, and the axis O of the filter 11 is located above the handle of the pipe wrench.

[0044] exist figure 1 Here, a band pipe wrench 10 comprises a handle 12 having a distal portion 13 and a proximal portion 14, the distal portion 13 forming a forked joint with wings parallel to the plane of the drawing.

[0045] The strap 15 is in particular a metal strap and forms an endless strap, the strap 15 comprising two end pieces 16 and 17 connected to the han...

Abstract

The strap pipe wrench (10) of the invention includes a shaft (12); a strap (15), a connection member (28) mobile relative to the shaft (12), means (30, 40, 46) for displacing said member, the shaft being provided with a bearing pad (18) on said object. The member is mobile between at least a first position corresponding to a loose strap position and a second position corresponding to a tensioned strap position tightly surrounding the object bearing on the pad (18), while the movement means include: blocking means for maintaining said member in a fixed position relative to the shaft (12) in the first position of said member; an elastic member (46) that urges said member towards the second position; and a control member (30, 40, 56) for deactivating said members.

Description

technical field [0001] The present invention relates to a belt-type pipe wrench for moving a generally cylindrical object, the belt-type pipe wrench comprising: [0002] - a portion extending along the longitudinal axis forming the handle; [0003] - a strap, in particular a metal strap, in the form of a loop, the two opposite end sections of which cooperate with the two areas connected to the handle when said strap is tightly encircled around said object; [0004] - a connecting mechanism movable along its longitudinal axis relative to said portion forming the handle, two opposite terminating sections of said strap each having an end connected to said connecting mechanism; [0005] - a moving part moving said connecting mechanism, said moving part allowing to adjust the size of the loop of the strap and to tension the strap as it tightly surrounds said object; [0006] - said part forming the handle is provided between said two regions with a support pad for support on said...
